<p>PROBLEM TO BE SOLVED: To provide a can making material excellent in machinability, adhesion, and corrosion resistance by using a specified aluminum raw material and forming multi-layer structure composed of a surface treatment layer chiefly containing a specified inorganic substance, a surface treatment layer chiefly containing a specified organic substance, and a layer coated with a specified polyester resin. SOLUTION: In an aluminum can material, the multi-layer structure in which the surface treatment layer chiefly containing an inorganic substance, the organic surface treatment layer chiefly containing an aqueous phenol resin, and the layer coated with the polyester resin are formed in turn is formed at least on the surface on the container inner surface side of an aluminum base material.</p> |
